The Devil is a Sweetheart

He was just a kid, an eight-year old boy when he was thrown into a lifetime of nightmares. What emerged was a guy so vicious, so ruthless that people called him the Devil. He had no heart, at least that's what they thought. He became an undercover agent, a street fighter, a street racer...he did everything he wanted to. The world was his for the taking and take it he did.
A summer afternoon, the kind you read in books and fairytales, he saw her. Running with a smile on her face so bright he smiled too. For the first time in 4 years he smiled genuinely and it was all because of that girl. She too, seemed to be straight out of a fairytale. The light to his dark.
Will she change him? Or will his dark past haunt them dooming him. Them.
